EDIT2: PeerTube is no longer using WebTorrent for Redundancy - see thread below
 
PeerTube has RSS feeds with WebTorrent links. You can grab those links and seed whatever content you wish using a WebTorrent client without having to install an entire PeerTube instance.

What does this do? It helps alleviate some of the streaming costs of servers and ensures a smoother experience for everyone on the decentralized web.

Yay for open source platforms!

A webtorrent client (the only webtorrent client?) that allows you to be a peer and seed data for the videos.
